Hi there ~
I understand your concerns. Smoking
hookah in itself may cause you to have shortness of breath
and depending on what was in the mixture that you smoked, having blurring vision may be part of it. I would ask you to avoid using the hookah and stop using it completely. I also think that you might do well with visiting a psychiatrist
who can get you off of your problem and get you on the path to health.
I hope this helps. Take care and have a lovely day!
